Despite a recent upturn in pace that saw it take two podiums in Hungary and prove competitive in Belgium, Red Bull expects to suffer on the long straights at the high-speed at Monza due to the limitations of the Renault power unit.

In anticipation of the difficulties, coupled to the expectation of being more competitive at the following Singapore Grand Prix, Horner says Red Bull will take new engines strategically in Italy.

"I'm fairly certain we'll be taking new engines for both cars, considering the amount of races left. It's inevitable that we'll be staring down the barrel of our next penalty of which strategically, Monza is the most likely. We don't want to be going into Singapore with old engines or any risk, that's really our next chance to shine."
